The Supercontinent Puzzle: How West Gondwana Was Born

Roughly 600 million years ago, three continents we know today — South America, Africa, and Antarctica — slammed together to form West Gondwana, one of the largest landmasses ever to exist on Earth. This is the geological road trip across deep time: how ancient oceans closed, mountain belts rose along continental margins, and a supercontinent was stitched together piece by piece. The evidence is still written in the rocks of Brazil, West Africa, and the frozen edge of Antarctica. 🗺️ Chapters: 00:00 Intro — A road trip across deep time 00:45 The Longest Edge: Earth's most ancient suture 01:30 What is West Gondwana? 02:30 Supercontinent Assembly: how landmasses collide 03:45 South America's Puzzle 04:45 Africa & Antarctica: the southern fit 05:45 Earth's Moving Margins 06:45 Why Gondwana still matters today West Gondwana was the western half of the larger Gondwana supercontinent — itself part of the even older Pannotia and Rodinia. Its assembly during the late Neoproterozoic involved the Brasiliano and Pan-African orogenies, vast mountain-building events that fused ancient cratons along thousands of kilometers of continental margin. The matching geology along the Atlantic coasts of South America and Africa is one of the strongest pieces of evidence for plate tectonics — the same evidence Alfred Wegener pointed to a century ago when he proposed continental drift. Today, those once-joined margins are split by the Atlantic Ocean, but the rocks remember. Identical rock formations, fossil belts, and ancient mountain roots line up across continents like torn pages of the same book.
